Systems and methods of preventing access to users of an access control system

摘要

Systems and methods are provided that include preventing access to users of an access control system, for example, by facilitating an administrator temporarily forbidding access by all users to one or more areas secured by one or more doors associated with one or more card readers. Some methods can include reading a first management card at a first card reader, identifying a first group of which the first card reader is a part, identifying a plurality of card readers in the first group, and updating a database device to indicate that access via the first card reader or any card reader in the plurality of card readers is forbidden.
